(PDF) The Role of Blockchain in 6G: Challenges, Opportunities, and Research Directions.
So this buzzword laden document was published by the IEEE. As far as I can tell it doesn't actually say much besides a breathless stream-of-consciousness about how blockchain and AI will make everything amazing and is terribly relevant to wireless communication protocols because reasons.
But... just read it. If you can make it to the end without your brain oozing out of your ears then you win the grand prize!
“Extreme edge”: 6G networks need to facilitate the spatial translation of many core services from the cloud to the edge networks for achieving extremely low latency communications and instant networks. The trustworthy coordination and transparent resource bookkeeping can be attained with blockchains in these systems [20].
In 4G, AI was not yet applied, while in 5G there is already a limited partial use. We expect a much deeper integration of AI on all levels of the 6G network communications with the ultimate goal to make our society super smart, super efficient and more green.
